    Question Dual Monitor / OpenGL Problems

    Hello,
    I've installed OpenSUSE 11.1 on a system with an ATI X600 series graphics card. OpenGL works fine on the main screen and half of the second screen. On the other half of the monitor OpenGL graphics are fuzzy/distorted. I believe I'm just using the xrandr driver.

    Does anyone have recommendations on how to correct this?

    Example:

    I'm continuing to do research but I believe this describes the problem I'm having:

    fglrx: openGL broken for screen width greater than
    1760 pixels (bug #450426)

    Bugs in package cgi in unstable -- Debian Bug report logs
    Since fglrx−driver 8.42.3−2 most of the openGL screen (either full screen or windowed) is corrupted when
    the width of the openGL window is more than 1760 pixels.
    The way it looks: top of the window (1/4 or so) looks OK, the rest of the screen is mostly obscured, i.e. some
    polygons are visible but the screen is mostly black.
    system:
    ATI Technologies Inc Radeon R350 [Radeon 9800 Pro] (using the secondary monitor in two monitor setup,
    primary is off)
    fglrx−driver−8.42.3−2, fglrx−driver−8.43.2−2 (both have same problem)
    any ideas? didn't find exactly the same problem on the net (found the one about the corruption of lower right
    corner which is much different symptom than the problem I have)
    given that this is openGL problem don't think that open drivers would help, they seem to not offer much 3D
    acceleration (and radeonhd says it works with R500/R600 only)
    any ideas?
    TIA,
    erik
